Reading this thread was fun. Probably not at all serious at this point, but I really wanna post...
-Swiss Army Knife/Pocket Knife (or both)
-Fire starting kit
-Blankets (black or gray, for hiding situations
-Emergency radio
-Very dark, black outfit
-Tiny water filter + bottle or two
-Crowbar!

A pair of these babies-A small, silenced pistol. Dunno what kind.
-Probably some kind of food item
This is assuming the zombies take on the '28 Days Later' style of infection. This is also assuming I'm going to make my way out of the city quickly and stealthily, avoiding any contact possible with infected (and non-infected) people. I would make use of shady/dark niches. I would also use the pistol if things got bad (ie. stumbling upon one infected) and getting the hell out quickly and quietly.
I would eventually make my way towards the woods, or any remote location, on foot and go as far out and away from civilization as possible. I would try to survive until the whole thing blew over, or everything died of starvation. I could also pick up a tree perch on my way out, just to make things a bit safer.
I'd probably die of starvation after realizing that my only survival skill came from a couple episodes of Survivor Man, but it would be a much prettier way to go than being torn apart by a horde of rabid people. :D
